I keep seeing adverts telling me that the digital switch over is coming and that although I can get it just fine on my main TV the other sets in the house will need set top box to receive digital. In truth it isn't really a problem where I live as we have ages yet before we switch over but...

Naw, power surge ate them man... Would cost more than they are worth to repair, so hope you did not have any personals on them. I have 4 server drives this happened to, over 4TB all gone to media heaven, no hope for them at all, 1,000's $'s to even think of recovering the media that was on them... FYI backup to a few sources and replace those sources as they wear out in a few years time on 24/7!
